Log Message:
-----------
SourceBuffer will always perform a sync call to GPU process when there's a
need to evict content.

Reviewed by Youenn Fablet.
Prior 275380@main, eviction was performed synchronously and the eviction data
algorithm would evict 3s of data at a time
until there was sufficient buffer space available for the appendBuffer
operation to complete.
In 275380@main, we pre-calculated how much data could be removed in total.
However, the calculation incorrectly
looked at the initial 3s of removable data only. Which would make the
SourceBuffer always consider that no data was evictable
preventing an asynchronous eviction to occur and instead generating a sync call
to SourceBufferPrivate::evictData.
Added tests.
